摘要
DNA is a dynamic molecule that undergoes constant changes in the cell through interactions with numerous proteins. Several classes of enzyme are specialized in promoting DNA rearrangements, including site-specific recombinases, DNA helicases, transposases and DNA topoisomerases. Recent structures of protein-DNA reaction intermediates trapped in various states of DNA remodeling, complemented by biochemical and biophysical functional studies, have enhanced our understanding of their respective mechanistic pathways.
